Free Greywater System Installer Service Agreement

One bad seal turns a client's basement into a swamp and your bank account into a crime scene. Without a solid contract, you're one 'misunderstanding' away from eating the cost of a three-thousand-dollar pump and a lawsuit that'll strip your gears.

Pro Contractor Tip

Hammer in a 'Pre-Existing Conditions' clause so you don't end up paying to fix the client's forty-year-old, rotting main line just because you touched a diverter valve.

Why use a written agreement?

Handshake deals are risky. As a Greywater System Installer, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

Frequently Asked Questions

The homeowner wants to 'save money' by buying their own pump—how do I protect myself when it dies?

Use an 'Owner-Furnished Equipment' clause to state you don't warranty their cheap parts; if their junk breaks, they pay your full hourly rate to pull it out and replace it.

How do I handle a client who keeps adding 'just one more' garden zone while I'm already digging?

Stop the shovel and point to the Scope of Work in your contract; tell them extra zones require a signed Change Order with an updated price before you move another inch of dirt.

The customer is dodging my final invoice because the grass isn't green yet—how do I get my check?

Ensure your contract defines 'substantial completion' as a functional mechanical system, not a landscaping result, so you can demand payment the moment the pressure test passes.
